The HWM2412U20WH is a 12U swing-out wall-mount rack cabinet with a vented front door, finished in RAL9003 white, built for mounting 19-inch rack equipment in IT and telecom environments that need a secure enclosure plus rear access. It suits network closets, telecom and data communication rooms, and government, education and commercial IT installations where active equipment needs airflow and serviceability.

Construction is mild steel: a 14-gauge welded rear section with a 16-gauge center section and doors, rated by UL2416 to 350 lb (159 kg) and seismic rated to 200 lb (90.72 kg) dynamic load (Ip = 1.5) per IBC 2018, CBC 2019, NBC 2018, ASCE 7-16 and ASCE 7-10. The powder coat finish is GREENGUARD Gold, TSCA and RoHS compliant, and the cabinet is TAA-compliant and manufactured in North America (country of origin CA), listed under UL file E474597.

This 12U size measures 27.75 in (705 mm) high x 24.68 in (627 mm) wide x 25.18 in (640 mm) deep with a 20 in center section depth; the product listing gives a nominal size of 27.81 in x 24.68 in x 25.67 in (706 mm x 627 mm x 652 mm). Mounting (usable) space is 21.00 in (533 mm) high x 19.00 in (483 mm) wide x 22.85 in (580 mm) deep, where the usable depth is the maximum equipment depth that still lets the body section swing out unimpeded. Shipping weight is 106 lbs (48.08 kg).

HWM2412U20WH ships with one pair of adjustable 10-32 threaded 19-inch mounting rails and a starter hardware pack of SCREW1032-50 screws. A heavy-duty spring-hinge mechanism controls swing-out access, the cabinet body is reversible on site to change swing direction, and multiple cable entry knockouts plus a rear opening support structured cable routing. Fan knockout patterns accept optional DNMF100AC115 or DNMF100AC230 fans, and power bar mounting is possible without using rack U space.
